This is a parametric pipe plug designed for sewer / drainage pipes with rubber seals (HT / KG systems).

The model is generated using OpenSCAD and supports pipe sizes from DN32 to DN110.
For convenience, I have also included pre-generated STL files for DN32, DN40, and DN50.

Features

  • Designed to fit pipes with rubber gaskets

  • Stop flange prevents the plug from being pushed in too far

  • Chamfered lead-in for easier insertion into the seal

  • Hollow interior to save material and reduce print time

  • Adjustable tolerance and wall thickness

  • Fully parametric – easily generate other DN sizes

Included Files

  • OpenSCAD source file (DN32–DN110)

  • STL files:

    • DN32

    • DN40

    • DN50

Recommended Print Settings

  • Material: PLA / PETG (PETG recommended for better durability)

  • Layer height: 0.2 mm

  • Infill: 20–30%

  • Perimeters: 3

  • No supports needed

  • Print orientation: flange on the build plate

Notes

This plug is intended for temporary or protective use, not for pressurized systems.

If you need a different DN size, simply change the parameter in OpenSCAD and export a new STL.
